DL Example generates error - Keras Network Learner

KNIME Extensions

Hi @kludikovsky ,

I’m sorry for the troubles you’re facing.

This thread here: An error occurred during training of the Keras deep learning network explains that the Keras nodes in KNIME require TensorFlow 1.x to work correctly.

Could you try switching your Python environment used for the DL Scripting nodes to one that uses Keras (standalone) and use TensorFlow 1.x (e.g., tensorflow==1.14)?

Or you can try using this workflow from @mlauber71: Sentiment Analysis - Setup with Conda Propagation. This uses the Conda Environment Propagation node, which automatically sets up a Python environment with all required packages for you.

Hope this helps.

Best,
Keerthan
